ABSTRACT:
A process for recovery of alkali values from trona ore comprising (a) dissolving the trona ore, (b) separating the insoluble material to obtain an alkali containing feed liquor, (c) cooling the feed liquor and crystallizing sodium bicarbonate and separating the bicarbonate crystals from the resulting mother liquor, (d) cooling the mother liquor and crystallizing sodium carbonate decahydrate and separating the decahydrate crystals from a weak liquor, and (e) treating the sodium carbonate decahydrate crystals to recover the alkali values therein.
